To all whom it may concern":

Be it known thatI;SIeM'UND L. GoLnM'Amf a citizen of the United States, residing at Chicago, in the county of Cook and State of? Illinois,have invented'a new and-useful Im- V provementv in Bottle Covers, of which the following isa specification. y i

My invention relates,'more particluarly,

to covers for milk bottles, provided for the purpose of closing themouthsof bottles and adapted to be manipulated into" a condition to permit of thepouring of the eontents from the bottle. 3 7 a g My objects generally stated, are to provide a novel, simple and inexpensive cont struction' of cover which will operate to perform the functions above stated,--in a highly efiicient' and desirable manner. More specifically certain of my objects *areto provide a construction 'of cover which may in ot the contents out of, the bottle; an-; 7 other object'is' to provide 'a con'struction the parts'of which may bereadily disassembled for cleansing and readily. r'e-as-I I sembled intov the proper relative positions,

the partsbeing readily cleansabl'e to reng der'the structure highly sanitary and other the follo w objects as will be manifest from description.

Feferring to the accompanying drawings Figure 1 is a plan view ofrmy'improved bottlecover showing' it as applied toa milk sliown asiri the form of a circular disk" "19: b Y which extends Withinthe recess 412,f.- This shutter is centrally apertured, as representbottle, the shutter device thereof being shown in open condition: 'Figure 2 1sIa similar View showing the shutterde iceqin closed position.

to extend entirely across it, and is provided at itsunder side where it contacts the'wall fiof the mouth,"wi th a washer 18 which is; located within the annular groove 10; this washer being constructed of any suitable i material preferably a material-which -will not be acted upon by. the casein contained-Y in'the milk Where the coverdevice is used as a cover for a milk bottleLsA' suitable" material for this purpose is rubberswhich' has been treated, as is well understood in the art, to render it not 'subject'tothe -dele- 1 terious action of casein?" If desired, the H Twasher 18 may be secured in'the groovlO: in any-desirable way, as, forfinstance, cementing it therein by the use of white T ishella r I i The cover devicealsocomprises a shutter ed at 20', the portionof'thexdisk surroun'd i ingthis aperture being-upwardly defiected, it

-The cover device also comprises a spring device shown as formed of a single strip .of spring metal, this spring device being represented at and extending across the topefthecover section. 9 and the shutter 19 16 as'shown The spring device 25 is of "considerably greater length then the diam: o eter-of the cover section-.9 and itsrdependi-n e extremities;represented; not: 26 converge I downwardly and terminate in bead portions 27,1asshownin F1g..;3,."jTl1e spring-device 25 is centrally apertured, as represented V V at 28f I 20 The cover section :9, shutter 19. and spring 1 device 25, are-heldtogether bymeans of a fastening devicecomprising a stud 2.9 secured in. the opening '13 in the: section 9 and extending upwardly, there'i'rom and presenting the; threaded: portion- 30., and a wingenuttlf which screws upon this threadedpjortionm The stud shown is formed at 1 itsilowenendwitha reduced-portiOnBQ-at WlllCllllt fits in the opening 13, its lower extremity being! upset, as: represented at" 33,

thejshutter :device is in thepositionshown i in Fig. 2 the openings therein are out of registration with the openings 14- and-15 in which position the cover is closed. When it 'isdesired to pour out the contents of the bottle, the shutterdevice is rotated to the position shown in Fig, '1 in which position the openings 22 andv 23 register with the openings 14; and 15 respectively, the openings 23 and 15' serving as the outlet for the contents of the bottle, and theopen ings 1e and 22 serving-as, an air vent permitting of the even flow of the fluid from.

the bottle. 7 The partsof the structure the spring device25 forms an -abutment for the lug 2 1 and when this lugengages this spring device as shown in Fig. ,1 the cover is rendered open as explained.

0116 of the advantages of my construc tion is that it maybe readily cleansed, this being accomplished by unscrewingthe:

wing-nut 31 whereupon the parts 9, 19 and 25. may be separated and independently cleansed as for example, by immersing themin boilingwater, it being noted that are preferably J so constructed andarranged, as shown, that the stud and wing-nut constitute a single unitary means .for holding these various parts togetherin operative relation,

The purpose ofythe projections 16 on the cover section 9 is to insure the soipositioning of the spring device ZS that the openings in the shutter and the cooperating openings in the section 9 willregister, when the lug 24 in the rotation of the shutter de-' vice in one direction, abuts the spring; device.

It will be-understood that by forming the cover device, as described. it is adaptedto be applied tobottles of difi'erent sizes as, for

, example, in the case of milk or cream bot vice 25,. The-wing-nut 31 upon being tight- 4 ened clamps {the spring device 25; between it; and the-shoulder- 3 L, the parts. described 7 being preferablysoiproportionedthatthe shuttera 1 3 may be rotated about -the studtles, to splits, pints or qu;arts,.-

particular construction embodying my in tlOlL;

. 1. A cover device comprising a platep'or- VVhileI have illustrated and described; a

What I claim as new; andwdesireto-secure by Letters Patent, is: e

.tionvadapted to extend acrossthe mouth of a bottle, a spring device extendingacrosso thev upper surface ofsaid plate-portion and presenting depending free sprin'gy-portions which extend-below the planeof. the under 7 surface of said plateeportion at opposite sides ofthe latter, said plate-portionqbeing.

apertured,rashutter cooperating with the- :apertured portion or said plate-portion and provided with projection cooperating with :the spring to form "a stop for limiting-the movement of the shutter, project-ions o-n :saidplate-portion for cooperation with'said spring in the applicationof .the latter to said plate-portion and so related to the-lat-- l0 a shutter controlling said aperture, a spring ter and to said shutter that when the latter is moved to a position in which the projection thereon engages said spring in one position of the shutter, a. discharge opening for the contents of the bottlevto which the device is applied is afio-rded, and means for holding saidspring device in place.

2. A cover device comprising a plate-portion j containing an aperture, a rotatable i portion adapted to extend across the mouth of a bottle, said plate-portion being formed on its upper surface at its central portion with a depression and presenting, an',annular groove on its under side, said plateportion being provided with upwardly-ere tending projections, the bottom of said de+ pression'containing an outlet aperture and ing an airvent opening and a fluid outlet an air vent, a washer in said groove, a shutter located in said depression andcontainso arranged that in one position ofsaid shutter the openings in the latter register with the corresponding openings in said plate-portion, said shutter being provided with an upwardly-extending lug and con tai'ning a stud-receivingaperture, a spring provided with depending end portions at which it is adapted to be clamped upon the neck of a bottle; said spring device being portion and forming astop for; the lug on said shutter in which position the apertures in said shutter register with the apertures in said plate-portion, a threaded stud ex-' tending through said shutter and spring device and engaging said plate-portion, and a nut screwing on the threaded portion of said stud for clamping the parts of-th'e cover device together.
